The disease of coronary vascular origin has been increasingly calling our attention in recent years in Japan, and it has played a prominent part in the diseases of circulation. Although various clinical examinations have been in use in the early detection of the coronary sclerosis resulting in the myocardial infarction or coronary insufficiency, none of them seem to be satisfactory for a diagnostic method of choice. The electrocardiographic examination after exercise had been found to be useful in the diagnosis of the latent coronary sclerosis, and many studies have been reported on this subject, however, no critical evaluation has yet been made on the change in the electrocardiogram after exercise test. The author has made the studies on the changes in the electrocardiogram after Master's exercise test with the one group suspected of the latent coronary sclerosis from their anginal symptoms or clinical examinations ; the other group showing normal electrocardiogram was chosen as the control. From these results, an attempt has been made to establish the clinical evaluation of the exercise test. In addition, the exercise test has been tried on patients with neurocirculatory asthenia simulating coronary sclerosis with the subjective complaints requiring differential diagnosis, and the comparative studies of electrocardiograms were made. Although practice of the exercise test was usually for healthy adults at rest demonstrating normal electrocardiographic tracings, the present investigation stressed in patients with abnormal electrocardiogram at rest and the results were evaluated by comparing between the exercise test in group with normal and abnormal electrocardiograms at rest together with the subjective complaints corroborated with clinical laboratory findings. Materials and Methods of Observation All subjects were classified into the following 4 groups. Group 1, 81 normal adults over 40 years of age. Group 2, 110 patients over 40 years of age who were suspected of coronary sclerosis from their subjective symptoms and the laboratory examinations, showing normal electrocardiogram in resting time. Group 3, 61 patients with the neurocirculatory asthenia. Group 4, 107 patients with the coronary sclerosis whose electrocardiograms showed coronary insufficiency with the symptoms, signs and laboratory examinations, revealing the characteristic findings.
